LTC4090/LTC4090-5
USB Power Manager with
2A High Voltage Bat-Track
Buck Regulator
DESCRIPTION
The
LTC
®
4090/LTC4090-5
are USB power managers plus
high voltage Li-Ion/Polymer battery chargers. The devices
control the total current used by the USB peripheral for
operation and battery charging. Battery charge current
is automatically reduced such that the sum of the load
current and the charge current does not exceed the pro-
grammed input current limit. The LTC4090/LTC4090-5
also accommodate high voltage power supplies, such as
12V AC/DC wall adapters, Firewire, or automotive power.
The LTC4090 provides a Bat-Track adaptive output that
tracks the battery voltage for high efficiency charging from
the high voltage input. The LTC4090-5 provides a fixed 5V
output from the high voltage input to charge single-cell
Li-Ion batteries. The charge current is programmable and an
end-of-charge status output (CHRG) indicates full charge.
Also featured are programmable total charge time, an NTC
thermistor input used to monitor battery temperature while
charging and automatic recharging of the battery.
